Condor 17
Yes it was Jarrolds..
I did a stint there before moving on to BY at LTN.
My job was to gather up school books that had been ordered by schools all over the eastern counties.
Once gathered books/ pens/pencils were all sent to the packing department for packaging and posting.
The packaging department was manned by 2 gents who were dispatched downstairs to be father Christmas's during the Christmas season.
These gents also did printing from memory so one may have been your father.
OU was Court Line.
